Session Initiation Protocol (SIP) Torture Test Messages for
Internet Protocol Version 6 (IPv6)
Status of This Memo
This memo provides information for the Internet community. It does
not specify an Internet standard of any kind. Distribution of this
memo is unlimited.
Abstract
This document provides examples of Session Initiation Protocol (SIP)
test messages designed to exercise and "torture" the code of an
IPv6-enabled SIP implementation.

1. Overview
This document is informational, and is *not normative* on any aspect
of SIP.
This document contains test messages based on the current version
(2.0) of the Session Initiation Protocol as defined in [RFC3261].
This document is expected to be used as a companion document to the
more general SIP torture test document [RFC4475], which does not
include specific tests for IPv6 network identifiers.
This document does not attempt to catalog every way to make an
invalid message, nor does it attempt to be comprehensive in exploring
unusual, but valid, messages. Instead, it tries to focus on areas
that may cause interoperability problems in IPv6 deployments.
2. Document Conventions
This document contains many examples of SIP messages with IPv6
network identifiers. The appendix contains an encoded binary form
containing the bit-exact representation of all the messages and the
script needed to decode them into separate files.

The IPv6 addresses used in this document correspond to the 2001:
DB8::/32 address prefix reserved for documentation [RFC3489].
Likewise, the IPv4 addresses used in this document correspond to the
192.0.2.0/24 address block as described in [RFC3330].
Although SIP is a text-based protocol, some of these examples cannot
be unambiguously rendered without additional markup due to the
constraints placed on the formatting of RFCs. This document uses the
<allOneLine/> markup convention established in [RFC4475] to avoid
ambiguity and meet the Internet-Draft layout requirements. For the
sake of completeness, the text defining this markup from Section 2.1
of [RFC4475] is reproduced in its entirety below:
Several of these examples contain unfolded lines longer than 72
characters. These are captured between <allOneLine/> tags. The
